Use sdbus++ python library for name conversion
Use sdbus++ python library for name conversion

This code attempts to come up with sdbus++ property names by
doing its own string manipulation.  That conversion is likely
wrong in the future.  Instead, import the sdbus++ python code
directly and call the appropriate function from it.
